Bookbinding device having a glue cartridge and, a glue cartridge receiving unit

Abstract

A glue cartridge ( 130 ) comprises a glue tank ( 101 ), a rotatable glue spreading roller ( 104 ) connected to the glue tank, which is arranged directly below the glue tank ( 101 ) and at least one rotation means ( 106, 107 ) usable from outside the glue cartridge ( 130 ) for rotating the glue spreading roller ( 104 ). The glue spreading roller ( 104 ) of the glue cartridge is designed so that the form of the glue spreading roller ( 104 ) prevents glue from escaping from the glue tank ( 101 ) when the glue spreading roller ( 104 ) is in place and takes glue from the glue tank ( 101 ) when the glue spreading roller ( 104 ) is rotated. A block ( 1360 ) of sheets to be bound to form a book is set in a bookbinding device ( 1300 ), and glue is spread on the spine ( 1362 ) of the block ( 1360 ) in such a way that glue is obtainable from an exchangeable glue cartridge ( 130 ) by using a receiving unit ( 150 ) for the glue cartridge ( 130 ).

The invention claimed is: 
     
       1. A bookbinding device ( 1300 ) in which a block ( 1360 ) of sheets to be bound to form a book is placeable, and with the aid of which glue is spreadable on the spine ( 1362 ) of the block ( 1360 ), the bookbinding device ( 1300 ) comprising:
 a glue cartridge ( 130 ) comprising: 
 a glue tank ( 101 ) that is essentially in the form of a protrusion from a platform ( 110 ) of the glue cartridge and where at least two sides of the platform ( 110 ) have a fastening device ( 102 ,  103 ,  108 ) to allow the shape-limited fastening of the glue cartridge ( 130 ); 
 a rotatable glue spreading roller ( 104 ) connected to the glue tank, which is arranged directly below the glue tank ( 101 ); and 
 at least one rotation means ( 105 ,  106 ,  107 ) usable from outside the glue cartridge ( 130 ) for rotating the glue spreading roller ( 104 ); 
 wherein the rotatable glue spreading roller ( 104 ) is configured so that the form of the glue spreading roller ( 104 ) prevents glue from escaping from the glue tank ( 101 ) when the glue spreading roller ( 104 ) is in place and takes glue from the glue tank ( 101 ) when the glue spreading roller ( 104 ) is rotated; 
 the bookbinding device ( 1300 ) further including a receiving unit ( 150 ) for the glue cartridge ( 130 ), wherein the receiving unit ( 150 ) comprises: 
 means ( 156 ,  157 ) for receiving and fastening the glue cartridge ( 130 ) to said receiving unit ( 150 ) in such a way that the glue spreading roller ( 104 ) is accessible from below, and thus allows gluing from above of the spine of a sheet block that is to be bound; and 
 at least one rotatable converter ( 153 ,  240 ,  152 ,  158 ) for transferring motion to at least one rotating means ( 105 ,  106 ,  107 ) in the glue cartridge ( 130 ); and 
 wherein glue is taken from the exchangeable glue cartridge ( 130 ) by using the receiving unit ( 150 ) for the glue cartridge ( 130 ). 
 
     
     
       2. The bookbinding device ( 1300 ) of  claim 1 , wherein the means ( 105 ,  106 ,  107 ) for rotating the rotatable glue spreading roller ( 104 ) comprises a shaft ( 105 ) and at least one shape-locking drive member ( 107 ) arranged with the shaft ( 105 ). 
     
     
       3. The bookbinding device ( 1300 ) of  claim 1 , wherein the glue tank ( 101 ) is essentially in the form of a cylinder, a cone or a truncated cone. 
     
     
       4. The bookbinding device ( 1300 ) of  claim 1 , further including a cap or a cover in order to close the glue cartridge. 
     
     
       5. The bookbinding device ( 1300 ) of  claim 1 , wherein the glue cartridge includes coding to express the glue cartridge type. 
     
     
       6. The bookbinding device ( 1300 ) of  claim 1  further including at least one heating unit ( 350 ) to heat the glue tank ( 101 ). 
     
     
       7. The bookbinding device ( 1300 ) of  claim 6  in which the heating unit ( 350 ) includes at least one heat transfer unit ( 410 ) which comprises a shell ( 411 ) and radial segments ( 412 ,  413 ), and which is configured so that the glue cartridge is off-center in the heating unit. 
     
     
       8. The bookbinding device ( 1300 ) of  claim 6 , in which the heating unit ( 410 ) comprises a hinged locking device ( 380 ) that is configured so that the locking device prevents the removal in a lateral direction of at least one heat transfer unit ( 350 ) and/or glue tank ( 101 ). 
     
     
       9. The bookbinding device ( 1300 ) of  claim 6 , in which the heating unit is formed by fastening two identical parts ( 380 ) to each other, and wherein at least one heat transfer unit ( 350 ) and/or glue tank ( 101 ) is locked in a lateral direction. 
     
     
       10. The bookbinding device ( 1300 ) of  claim 1 , further including means to express the coding in the glue cartridge ( 130 ). 
     
     
       11. A bookbinding device ( 1300 ) according to  claim 1 , wherein the glue spreading unit ( 1310 ) is movable in a backwards and forwards direction and which is configured to rotate the glue spreading roller ( 104 ) of the exchangeable glue cartridge ( 130 ) when the glue spreading unit ( 1310 ) is moved backwards and forwards, in which case the glue in the glue tank ( 101 ) can be spread on the spine of the block ( 1360 ) of sheets. 
     
     
       12. A bookbinding device ( 1300 ) according to  claim 1  further including at least one heating unit ( 350 ) configured to heat the glue tank ( 101 ), wherein the at least one heating unit ( 350 ) includes at least one heat transfer unit ( 410 ) which comprises a shell ( 411 ) and preferably radial segments ( 412 ,  413 ), and which is most advantageously configured so that the glue cartridge is off-center in the heating unit;
 wherein the receiving unit ( 150 ) of the glue cartridge ( 130 ) further includes means to express the coding in the glue cartridge ( 130 ); and 
 
       wherein the bookbinding device ( 1300 ) is configured to adjust
 i) either a temperature and/or a heating power of the glue tank ( 101 ), or 
 ii) a temperature and/or a heating power of the heating unit ( 410 ), or 
 iii) a temperature and/or a heating power of both the glue tank and the heating unit as specified in the means to express the coding of the glue cartridge ( 130 ).
